▓▓ Cable Construction
Caledonian medium voltage cables are manufactured using the monosil process. Caledonian
provides the highly specialized plant, state-of-the-art research facilities and meticulous quality
control procedures that are required for the manufacturing of PVC insulated cables for use up
to 6KV and XLPE/EPR insulated cables for use at voltages up to 42 KV. The materials are all
kept in cleanliness-controlled conditions throughout the production process in order to ensure
the absolute homogeneity of the finished insulation materials.
Conductors
Either aluminium or copper conductors are used. Conductors up to 800mm² will be circular,
compacted & stranded and shall comply with IEC 60228 class 2. 1000mm² conductor will be
circular stranded type on which a layer of semi-conducting tape will be applied.
Conductor Screen
This will be an extruded layer of semi-conducting crosslinkable compound applied under
simultaneous triple extrusion process over the conductor along with the insulation and the
insulation screen. The triple extrusion is a single high precision operation that eliminates the
possibility of any contamination between the layers which could create irregularities in the
electrical field. By careful material selection and special attention to process parameters,
Caledonian produces the insulation screen layers with the required degree of stripping force
as stipulated by the applicable national or international standard.

Insulation
This will be an extruded layer of XLPE or EPR applied over conductor screen under triple
extrusion process along with conductor screen and insulation screen. PVC may be used for
1.8/3KV and 3.6/6KV cables.
Insulation Screen
This will be a layer of semi-conducting crosslinkable compound which will be applied by triple
extrusion process over the insulation.
Metallic Screen
It will consist of a layer of copper tape applied helically with overlap over insulation screen.
Other combinations of metallic screens as per customer’s requirement can also be provided
on request.
Laying-Up
In case of three core cables, the three cores are laid up with non-hygroscopic fillers like
polypropylene(PP) fillers at interstices and a binder tape is applied with an overlap. These
binder tapes can be of PVC or foamed Polyethylene.
Inner Sheath (Bedding) for Armoured Cables
Extruded layer of PVC or PE is applied over the laid up cores for armoured cables. PVC is
normally of grade ST2 and PE of grade ST7 as per IEC 60502 Part 2.
Armouring
In case of armoured cables, the armour is applied helically over inner sheath. For single core
cables, it is of aluminium wires and for multicore cables, the armour can be of one among the
following options:
a) Galvanized steel wire.
b) Galvanized steel tape.
c) Galvanized steel strip.
Oversheath
An extruded layer is applied over the armour in case of armoured cables and over laid up
cores in case of unarmoured cables. Outer sheath material can be either PVC, PE, HDPE or
MDPE. Caledonian medium voltage cables are normally supplied with red PVC oversheaths
complying with BS 6622 or IEC 60502. Other colors may be provided to suit a range of
installation considerations such as the effect of UV radiations and differing soil compositions.
Anti-termite formulations can also be supplied in addition to graphite-coated oversheaths
where on-site testing of the sheath is required.

Insulaton Screen: Extruded layer of semi-conducting cross-linkable compound is applied
over the insulation. The extruded semi-conducting layer shall consist of bonded or cold
strippable semi-conducting compound capable of removal for jointing or terminating. As an
option, a semi -conducting tape may be applied over the extruded semi-conducting layer as a
bedding for the metallic layer. The minimum thickness is 0.3 mm and the maximum resistivity
is 500 Ohm-m at 90°C. The screen is tightly fitted to the insulation to exclude all air voids and
can be easily hand stripped on site.
Inner Covering & Fillers: For cables with a collective metallic layer or cables with a metallic
layer over each individual cores with additional collective metallic layers, semi-conducting
inner covering and fillers shall be applied over the laid up cores. The inner covering is made
of non hygroscopic material, except if the cable is to be made longitudinally watertight. The
inner covering shall be extruded or lapped.
The approximate thickness of extruded inner coverings is given in Table 2:

*The approximate thickness of lapped inner coverings shall be 0.6mm.
Metallic Layer: The metallic layer shall be applied over each core or applied as a collective
screen. The metallic screen shall consist of either copper tapes or a concentric layer of
copper wires or a combination of tapes and wires. The metallic layer provides an earth
fault current path, capable of withstanding fault current to earth of 1000A for one second at
maximum temperature 160°C. Copper wires are applied over the conducting water blocking
layer with a minimum diameter of 0.5mm. And over the copper wires, copper tape with
minimum thickness of 0.1mm can be applied helically with overlap.
Total cross section of copper wire screen is shown in table 3.

Over Sheath: Overall sheath comprises a layer of extruded either PVC type 9 conforming
to BS 7665-4.2 or MDPE type TS2 conforming to BS 7655-10.1; LSZH can be offered as an
option. The oversheath is normally black in colour. When a DC voltage test is to be performed
on the oversheath, a semi-conducting layer such as graphite coating shall be applied over
the surface of the extruded oversheath. The nominal oversheath thickness is calculated
by 0.035+D where D is the diameter immediately under the oversheath in mm. For cables
with the oversheath not applied over the armour, the nominal oversheath thickness shall not
be less than 1.4mm. And for cables with oversheath applied over the armour, the nominal
oversheath thickness shall not be less than 1.8mm.

*Insulation Thickness of PVC is 3.4mm (1- 1600mm sq) for 3.6/6KV cables.
Medium Voltage Cables to IEC 60502
Insulaton Screen: The insulation screen consists of an extruded layer of non metallic, semiconducting compound extruded over the insulation. The extruded semi-conducting layer
shall consist of bonded or cold strippable semi-conducting compound capable of removal
for jointing or terminating. As an option, a semi-conducting tape may be applied over the
extruded semi-conducting layer as a bedding for the metallic layer. The minimum thickness
is 0.3 mm and the maximum resistivity is 500 Ohm-m at 90°C. The screen is tightly fitted to
the insulation to exclude all air voids and can be easily hand stripped on site. The insulation
screen is not necessary for both PVC and EPR/HEPR insulated 1.8/3KV and 3.6/6KV cables.
The screen may be covered by semi-conductive water blocking swellable tape to ensure
longitudinal watertightness.
Metallic Layer: The metallic layer may be applied over the individual cores or the core
assembly collectively.
The following types of metallic layers are provided:
1) Metallic Screen
2) Concentric Conductor
3) Metallic Sheath
4) Metallic armour
The metallic screen shall consist of either copper tapes or a concentric layer of copper wires
or a combination of tapes and wires to provide an earth fault current path. The concentric
conductor is applied directly either over the insulation, or over the insulation screen or over
an inner covering. The metallic sheath consists of lead or lead alloy applied as a tightly fitting
seamless tube. The metallic armour consists of either flat wire armour, round wire armour,
and double tape armour.

Separation Sheath (for armoured cable): The separation sheath comprises a layer of
extruded PVC, PE or LSZH, applied under the armour .The nominal thickness is calculated
by 0.02Du + 0.6mm where Du is the fictitious diameter under the sheath in mm. For cables
without a lead sheath, the nominal separation sheath thickness shall not be less than
1.2mm. For cables where the separation sheath is applied over the lead sheath, the nominal
separation sheath thickness shall not be less than 1.0mm.
Lapped Bedding (for armoured lead sheathed cable): The lapped bedding consists of
either impregnated/synthetic compounded paper tapes or a combination of two layers of
these paper tapes followed by a few layers of compounded fabulous materials. The thickness
is around 1.5mm.
Armour (for armoured cable): The armour consists of round aluminium wire armour applied
helically over an extruded separation sheath.

Over Sheath: Overall sheath comprises a layer of extruded thermoplastic compound (PVC,
PE or LSZH can be offered as an option.) or elastomeric compound (polychlorprene CSP or
chlorosulfonated PE). The nominal oversheath thickness is calculated by 0.035D+1 where D
is the fictitiuous diameter immediately under the oversheath in mm. For unarmoured cables
and cables with the oversheath not applied over the armour, metallic screen or concentric
conductor, the nominal oversheath thickness shall not be less than 1.4mm. And for cables
with oversheath applied over the armour, metallic screen or concentric conductor, the nominal
oversheath thickness shall not be less than 1.8mm.

Three Core Cables to IEC 60502
▓▓ APPLICATIONS:
The three core cables are designed for distribution
of electrical power with nominal voltage Uo/U
ranging from 1.8/3KV to 26/35KV and frequency
50Hz. They are suitable for installation mostly
in power supply stations, indoors and in cable
ducts, outdoors, underground and in water as well
as for installation on cable trays for industries,
switchboards and power stations.
▓▓ STANDARD:

Armour(optional)
Conductor: Plain annealed copper or aluminium complying with IEC 60228 class 1 or 2.
Conductor Screen: The conductor screen consists of an extruded layer of non metallic,
semi-conducting compound applied on top of a semi-conducting tape. The conductor screen
is applied under triple extrusion process over the conductor along with the insulation and the
insulation screen. The extruded semi-conducting compound is firmly bonded to the insulation
to exclude all air voids and can be easily hand stripped on site. The conductor screen is not
necessary for both PVC and EPR/HEPR insulated 1.8/3.6KV and 3.6/6KV cables.
Insulation: Insulation is of polyvinyl chloride (PVC) intended for 1.8/3.6KV and 3.6/6KV
cables, cross-linked polyethylene compound (XLPE) or ethylene propylene rubber (EPR/
HEPR).

Insulaton Screen: The insulation screen consists of an extruded layer of non metallic,
semi-conducting compound extruded over the insulation of each core. The extruded semiconducting layer shall consist of bonded or cold strippable semi-conducting compound
capable of removal for jointing or terminating. As an option, a semi-conducting tape may be
applied over the individual cores or core assembly as a bedding for the metallic layer. The
minimum thickness is 0.3 mm and the maximum resistivity is 500 Ohm-m at 90°C. The screen
is tightly fitted to the insulation to exclude all air voids and can be easily hand stripped on site.
The insulation screen is not necessary for both PVC and EPR/HEPR insulated 1.8/3.6KV and
3.6/6KV cables. The screen may be covered by semi-conductive water blocking swellable
tape to ensure longitudinal watertightness.
Inner Covering & Fillers: For cables with a collective metallic layer or cables with a metallic
layer over each individual cores with additional collective metallic layers, semi-conducting
inner covering and fillers shall be applied over the laid up cores. The inner covering and fillers
are made of non hygroscopic material like polypropylene, except if the cable is to be made
longitudinally watertight. The inner covering is extruded in general but may be lapped if the
interstices between the cores are filled.
The approximate thickness of extruded inner coverings is given in Table 2:

*The approximate thickness of lapped inner coverings shall be 0.4mm for fictitious diameters over the laid up cores up to and including
40mm and 0.6mm for larger diameter.
Metallic Layer: The metallic layer may be applied over the individual cores or the core
assembly collectively. The following types of metallic layers are provided:
1) Metallic Screen
2) Concentric Conductor
3) Metallic Sheath
4) Metallic Armour
The metallic screen shall consist of either copper tapes or a concentric layer of copper wires
or a combination of tapes and wires. The concentric conductor is applied directly over the
inner covering. The metallic sheath consists of lead or lead alloy applied as a tightly fitting
seamless tube. The metallic armour consists of either flat wire armour, round wire armour,
and double tape armour.

Separation Sheath (for armoured cable): The separation sheath comprises a layer of
extruded PVC, PE or LSZH applied over the laid up cores under the armour. PVC is normally
of grade ST2 and PE of grade ST7. The nominal thickness is calculated by 0.02Du + 0.6mm
where Du is the fictitious diameter under the sheath in mm. For cables without a lead sheath,
the nominal separation sheath thickness shall not be less than 1.2mm. For cables where the
separation sheath is applied over the lead sheath, the nominal separation sheath thickness
shall not be less than 1.0mm.

Lapped Bedding (for armoured lead sheathed cable): The lapped bedding applied to
the lead sheath consists of either impregnated/synthetic compounded paper tapes or a
combination of two layers of these paper tapes followed by a few layers of compounded
fabulous materials. The thickness is around 1.5mm.
Armour (for armoured cable): The armour is applied over the inner covering helically. It
consists of either flat galvanized steel wire armour (strip), round galvanized steel wire armour,
and double steel tape armour.

For flat wire armour and fictitious diameter under the armour greater than 15mm, the nominal
thickness of the flat steel wire diameter shall be 0.8mm.Cables with fictitious diameter under
the armour up to and including 15mm, flat wire armour will not be used. The tape armour is
applied helically in two layers so that the outer tape is approximately central over the gap
of the inner tape. If tape armour is used, the inner covering shall be reinforced by taped
bedding.
Over Sheath: Overall sheath comprises a layer of extruded either thermoplastic compound
(PVC ST3 type or PE ST7 type) or elastomeric compound (polychlorprene CSP or
chlorosulfonated PE). The nominal oversheath thickness is calculated by 0.035D+1 where D
is the fictitiuous diameter immediately under the oversheath in mm. For unarmoured cables
and cables with the oversheath not applied over the armour, metallic screen or concentric
conductor, the nominal oversheath thickness shall not be less than 1.4mm. And for cables
with oversheath applied over the armour, metallic screen or concentric conductor, the nominal
oversheath thickness shall not be less than 1.8mm.

▓▓ CONSTRUCTION:
Conductor: Stranded compacted circular copper or aluminium conductors according to IEC
60228 class 2 / VDE 0276 class 2 / VDE 0295 HD 383. All internal interstices of the conductor
are filled with water blocking compound to prevent ingress of water through conductor during
storage, handing, installation and operation of the cable.
Conductor Screen: The conductor screen consists of an extruded layer of non metallic,
semi-conducting compound firmly bonded to the insulation to exclude all air voids. The screen
has a minimum thickness of 0.3mm and the maximum volume resistivity of 500 Ohm-m at
90°C.
Insulation: Insulation is of extruded XLPE compound type 2XI1 according to DIN VDE 0207
part 22 and HD 620.1 with high degree of cross-linking, free from contaminants, air voids and
heat resistant by dry cured process.
The nominal insulation wall thickness is shown in table 1.

Insulation Screen: The insulation screen consists of extruded non metallic, semi-conducting
compound extruded over the insulation. The extruded semi-conducting layer shall consist
of bonded or cold strippable semi-conducting compound capable of removal for jointing or
terminating.The minimum thickness is 0.3mm and the maximum volume resistivity of 500
Ohm-m at 90°C. The screen is tightly fitted to the insulation to exclude all air voids and can
be easily hand stripped on site.
Conducting Water Blocking Layer: The insulation screen may be coverd by semiconductive water blocking tape which will swell up under the influence of moisture of water to
ensure longitudinal watertightness.
Metallic Screen: Copper wires are applied over the conducting water blocking layer with a
minimum diameter of 0.5mm. And over the copper wires, copper tape with minimum thickness
of 0.1mm is applied helically with overlap. Total cross section of metallic screen layer is
shown in table 2. The screen can withstand fault current to earth of 1000 A for one second at
maximum temperature of 160°C. Minimum cross section of concentric conductor is according
to DIN VDE 0273 & 0276 as shown.

▓▓ CONSTRUCTION:
Conductor: Stranded compacted circular copper or aluminium conductors according to IEC
60228 class 2 / VDE 0276 class 2. VDE 0295 HD 383. All internal interstices of the conductor
are filled with water blocking compound to prevent ingress of water through conductor during
storage, handing, installation and operating of the cable.
Conductor Screen: The conductor screen consists of an extruded layer of non metallic,
semi-conducting compound firmly bonded to the insulation to exclude all air voids. The screen
has a minimum thickness of 0.3mm and the maximum volume resistivity of 500 Ohm-m at
90°C.
Insulation: Insulation is of extruded XLPE compound type 2XI1 according to DIN VDE 0207
part 22 and HD 620.1 with high degree of cross-linking, free from contaminants, air voids and
heat resistant by dry cured process.

Insulation Screen: The insulation screen consists of extruded non metallic, semi-conducting
compound extruded over the insulation. The extruded semi-conducting layer shall consist
of bonded or cold strippable semi-conducting compound capable of removal for jointing or
terminating. The minimum thickness is 0.3mm and the maximum volume resistivity of 500
Ohm-m at 90°C. The screen is tightly fitted to the insulation to exclude all air voids and can
be easily hand stripped on site.
Conducting Water Blocking Layer: The insulation screen may be covered by semiconductive water blocking tape which will swell up under the influence of moisture of water to
ensure longitudinal watertightness.
Metallic Screen: Copper wires are applied over the conducting water blocking layer with
a minimum diameter of 0.5mm. And over the copper wires, copper tape with minimum
thickness of 0.1mm is applied helically with overlap. Total cross section of metallic screen
layer is shown in table 2. The screen can withstand of fault current to earth of 1000 A for one
second at maximum temperature of 160°C. Minimum cross section of concentric conductor is
according to DIN VDE 0273 & 0276 as shown.

Technical information
▓▓ Current Ratings
The current ratings given on the previous pages are based on the standard conditions of
installation detailed bellows:
Maximum conductor temperature: 90°C
Maximum ambient temperature: In air 30°C
In ground 20°C
Ground thermal resistivity:
1.5K•m/W
Laying depth:
0.8m
Spacing between cable laid: In flat formation
2 times of cable overall diameter
In trefoil
with cable touching
Where the site conditions differ from the standard conditions mentioned, it will be necessary
to multiply the tabulated ratings by the actors given in the following tables. These factors are
for variation in ambient ground temperature, soil thermal resistivity and depth of laying. Where
more than one circuit is installed in close proximity, then will be necessary to derate further in
accordance with the group rating factors given.

Effect of grouping cables
No reduction in rating is necessary where there is free circulation of air around the circuits
providing that:
111 The horizontal clearance between circuits is not less than twice the overall diameter of an
individual cable.
222 The vertical clearance between circuits is not less than four times the diameter of an
individual cable.
333 If the number of circuits exceeds three, they are installed in a horizontal plane.
